WILLIAM H. V. ROSING, OE PRINGFIELD, IMISSOURI.

FREIGHT-CAR DOOR.

Application filed March 18, 1915.

To all whom it may concern Be it lmown that I, \VILLIAM H. V. RosiNe, a citizen of the United States, and a resident of the city of Springfield, county of Greene, and State of Missouri, have invented a certain new and useful Improvement in Freight- Car Doors, of which the following is a specification.

This invention relates to means for weather-proofing the top and side edges of sliding doors of box cars and the like.

The invention can be applied to existing box cars of various designs by slightly altering the door and its supports.

The object of the invention is a sliding hanging box car door which is proof against entrance of snow, water, cinders and the like, which hangs loose at all times, and

which has sufficient side play to prevent it from binding or sticking in any position of its movement.

The invention consists in a combined track and Weatherstrip secured to the car over the top of the door, in combination with a Weatherstrip secured on the top ofthe door itself.

The invention also consists in the door and door post construction whereby vertical drain channels are interposed in the path of entering water at the front and back edges of the door and the invention further consists in the parts and combinations of parts hereinafter more fully described.

What the invention comprises is more particularly set forth in the appended claims.

The preferred form of the invention is illustrated in the device shown in the accompanying drawings, wherein the same reference characters are used to designate like parts in the several views.

In the drawings Figure 1 is a side view of the middle portion of a box car having a door embodying my invention, Fig. 2 is a vertical cross-section through the eaves of the car and the upper part of the door, on the line 22 in Fig. 1; Fig. 3 is a horizontal cross-section through the car side and the front edge of the door on the lines 33 in Fig. 1, showing the door in closed position; and Fig. 4 is a horizontal cross-section through the car side and the back edge of the door, on the line 1- 1 in Fig. 1, likewise showing the door in closed position.

The invention is shown applied to a wood frame box car of ordinary construction, having wood side sheathing 11 and roof Specification of Letters Patent.

boards 12, but it may be applied to steel frame cars also. The door 13 is supported by means of hangers 14: from a track 15 which is bolted to the fascia 16 and side plate 17 over the door opening, and extends along under the eaves of the car to one side of the door opening far enough for the door to be slid clear of the opening. The door hangs freely from the track in all positions. Tts lower edge is prevented from swinging more than a quarter of an inch or so away from the car side by clips or brackets 18 which are bolted to the side of the car below the lower edge of the door.

A Z-shaped door stop 19 is bolted to the door post 20 on the side of the opening away from which the door slides. Angle clips or stops 21 are bolted to the side of the car below the far end of the track 15 to engage the back edge of the door and stop it at the end of its opening movement. The stops 21 engage the back edge of the door before the front end of its lower edge escapes from behind the nearer bracket 18. A metal strap 22 is arranged along the side of the car from the door opening to the end of the movement of the door to keep the door from scraping against the side of the car. The door may be provided with a hasp or any suitable fastening or locking device for holding it closed.

The track 15 is a pressed or rolled metal angle iron approximately Z-shape in crosssection, as shown in Fig. 2. The upper leg of the Z-shape track is bolted flatwise to the car, and the middle web projects out over the top of the door and constitutes a horizontal track for the rollers 23 of the door hangers to roll on. The lower leg of the Z-shape track is bent in on a slant toward the side of the car and terminates in a narrow vertical flange 24; which is parallel to the car side and is spaced a quarter of an inch or so away from it. The top of .the door is fitted with a weather strip 25 of angle shape, arranged over its outer edge. The inner edge of the angle strip has an upstanding flange 26 which projects up between the lower flange 24: of the track 15 and the side of the car, and the top edge of the upstanding flange 26 is bent out horizontally beneath the horizontal middle portion of the track. This flange 26 will hook over the inwardly bent lower leg of the Z-shaped track and support the door in case one or both of the hangers should break. A space 27 of considerable size is inolosed beneath the track between the lower leg thereof and the upstanding flange 26. Any water which may blow under the edge of the flange 24 will be trapped in this space and will be prevented from driving into the car. The front edge of the door is provided with a vertical rabbet or corner groove'28 its inner edge extending from top to bottom. In the closed position of the door this rabbet forms a vertical channel between the door and the end stop 19 within which any water which may flnd its way around the end of the door will be trapped and will run down outside of the car.

The door posts 20 project out beyond the car siding, and-the door hangs an inch or so clear of the siding. The back edge of the door is provided with a vertical heel strip 29 which extends from top to bottom of the door and projects inward toward the car siding. The inner edge of the heel strip rubs against the strap 22 on the side of the car when the door is opened and keeps the door clear of the car side. A weather strip 30 is secured along the outer side of the door post 20 on the side of the opening toward which the door opens. The edge of the weather strip 30 projects beyond the edge of the door post, and forms a vertical channel 31 between it and the side of the car. In the closed position of the door, the inner edge of the heel strip 29 closes the open side of the channel 81 and forms a vertical space within which any water which may find its way behind the edge of the heel strip will be trapped and will rundown outside of the car.

From the preceding description it is evident that the door hangs loose from the track in all positions, and that the weather strips do not bind the door or interfere in any way with its free sliding movement. Moreover, the car can suffer considerable distortion without cramping or binding the door, for the reason that there are no snug fits or tightly clamped parts to become jammed.

The invention is not restricted to the pre cise forms and arrangements of the parts shown in the drawings.

I claim the following as my invention:

1. A car door construction comprising a edges and spaced apart along their upper edges.

2. A car door construction comprising a track secured to the car above the door, said track having a horizontally extending portion overlying the top of the door and a depending inwardly bent flange along its outer edge, a door hanger having a roller running on the upper side of thehorizontal portion of said track, and a door suspended from said hanger, said door having a weather strip along its top edge provided with an upwardly projecting flange having an outturned top edge between said depending flange and the side of the car.

3. A car door construction comprising a track secured to the car above the door, said track having a horizontally extending portion overlying the top of the door and a de' pendingflange along its outer edge provided with a downwardly and inwardly inclined lower portion, and a door suspended fronr said track, said door having a weather strip along 1ts top edge provided with an upwardly projecting flange. between tlie-down wardly and inwardly inclined portion of said depending flange and the side of. the car, said flange having an outwardly extending upper edge portion with its extremity arranged above and in-proximity to the inwardly extending portion of said depending flange and adapted to support said door from said track in case of failure of the door suspending means.
